I own a Nissan 2007 350Z auto, I travel long distances in it for work. At the 100k service I the fuel throttle was replaced and the mechanic once installed had issues getting the car to start or idle. Since then every so often when driving the vehicle's dash lights up and slow the vehicle down to 5kmh.
Once complete the reset function the car returns to normal. Have had a few mechanics look at it and they all say the car is fine including Nissan. Does anyone have any ideas or have had the similar problem.
